Nosov D. The Efficiency Increase of Electroarc Surfacing Process in Combined Magnetic Fields

The object - the technological process of arc surfacing by a wire under the flux in combined magnetic field (СMF). The subject - the process of bead forming during the arc surfacing by a wire under the flux with СMF action. The purpose - effectiveness increasing of electric arc surfacing process under the flux during the action of outer СMF. The methods - calculation and experimental researches on the installations with standard methods and equipment use in laboratory conditions. The results - it has been proved that during the arc surfacing by a wire under the flux with СMF action asymmetric bead from in a cross-section can be obtained and to raise hardness of metal surfaced, the coefficient of alloying elements, the strength and yield limit, relative elongation and relative narrowing, to decrease the quantity of non-metal inclusion. At has been established, that in the zone of thermal influence the temperature fluctuations correspond the frequency of cross constituent of CMF. The methods of determination of conditions surfacing parameters with CMF have been developed, which provide minimum part of the basic metal in surfaced one, maximum surfacing productivity, tolerance decreasing to mechanical treatment, improvement of structural metal condition and increasing of surfaced article durability whish inculcation allowed to obtain a considerable economic effect in industrial conditions. The filed of application-machine - building enterprises (surfacing).
